Abstract
The present invention relates to the various method for testing performance of a kind of new product, the tangential loading method of especially a kind of wheel rim, belongs to Test And Check Technology field.The tangential loading method of a kind of wheel rim, by wirerope-winding on the loading wheel needing to detect, ensure that not relative sliding is taken turns in wire rope and loading, the two ends of wire rope connect left and right chest expander respectively, left and right chest expander is fixed on platform, and platform keeps constant with the distance loading wheel center.Left and right chest expander produces pulling force, and direction of pull is tangent with wheel rim all the time, and being loaded wheel rim can rotate simultaneously, so just can realize the tangential loading of wheel rim on-fixed point.The inventive method is simple, realizes easily, can realizing the tangential loading of wheel rim on-fixed point.
Description
Technical field: the present invention relates to the various method for testing performance of a kind of new product, the tangential loading method of especially a kind of wheel rim, belongs to Test And Check Technology field.
Background technology: in Design of Industrial Product, needs to carry out various performance test to new product.Along with the raising of technical merit, load mode is more and more close to actual condition.It is the load mode often used that wheel rim tangentially loads, for special loading requirement, such as wheel have necessarily rotate time, wheel rim minimum point is tangentially loaded, is exactly that on-fixed point loads, is difficult to realize.Therefore, how providing wheel rim on-fixed point tangential loading method, is the technical barrier that those skilled in the art need to solve.
Summary of the invention: for above-mentioned the deficiencies in the prior art, the invention provides the tangential loading method of a kind of wheel rim, effectively can carry out wheel rim on-fixed point and tangentially load.
For achieving the above object, the technical solution used in the present invention is: the tangential loading method of a kind of wheel rim, by wirerope-winding on the loading wheel needing to detect, ensure that not relative sliding is taken turns in wire rope and loading, the two ends of wire rope connect left and right chest expander respectively, left and right chest expander is fixed on platform, and platform keeps constant with the distance loading wheel center.Left and right chest expander produces pulling force, and direction of pull is tangent with wheel rim all the time, and being loaded wheel rim can rotate simultaneously, so just can realize the tangential loading of wheel rim on-fixed point.
The inventive method is simple, realizes easily, can realizing the tangential loading of wheel rim on-fixed point.
Accompanying drawing illustrates:
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of embodiment 1.
Embodiment:
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical scheme in the embodiment of the present invention carry out clear, intactly describe, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Give the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1
As Fig. 1 shows: carry out wheel rim on-fixed point to the wheel of undercarriage and tangentially load, machine undercarriage, comprise undercarriage and fix main pillar 1, undercarriage buffer 2, undercarriage lower shake-changing arm 3, undercarriage wheel 4.Undercarriage is fixed main pillar 1 and is connected with undercarriage lower shake-changing arm 3 axle.The two ends of undercarriage buffer 2 connect undercarriage respectively and fix main pillar 1 and undercarriage buffer 2.Undercarriage wheel 4 is fixed on the axle of undercarriage lower shake-changing arm 3 lower end.Be wrapped in by wire rope 5 on undercarriage wheel 4, the non-protruding part of wire rope 5 and wheel rim are fixed.The two ends of wire rope 5 connect right oil cylinder 6 and left oil cylinder 7 respectively.Right oil cylinder 6 and left oil cylinder 7 are fixed on platform 8.By system-computed, drive platform 8, ensure that platform 8 is constant with the distance at wheel 4 center, ensure that right oil cylinder 6 is consistent with required direction with left oil cylinder 7 loading direction simultaneously; Input system is composed on road, and according to road spectrum, right oil cylinder 6 and left oil cylinder 7 apply tangential pulling force by the point of contact of wire rope 5 pairs of undercarriage wheel 4 wheel rims; So just can realize the tangential loading of wheel rim on-fixed point, detect the fatigue behaviour of undercarriage wheel.
Claims (2)
1. the tangential loading method of wheel rim, it is characterized in that: wirerope-winding is taken turns in the loading that needs detect, ensure that not relative sliding is taken turns in wire rope and loading, the two ends of wire rope connect left and right chest expander respectively, and left and right chest expander is fixed on platform, and platform keeps constant with the distance loading wheel center, left and right chest expander produces pulling force, direction of pull is tangent with loading wheel rim all the time, and being loaded wheel rim can rotate simultaneously, so just can realize the tangential loading of wheel rim on-fixed point.
2. the tangential loading method of a kind of wheel rim as claimed in claim 1, is characterized in that: described left and right chest expander be oil cylinder, electric cylinder or other can servo-controlled actuator.
